三车道有管理元胞自动机交通流模型的研究

Study on a Three-lane Controlled Cellular Automata Traffic Model

在三车道元胞自动机交通流模型的基础上,将第1车道规定为超车道,对超车道上车辆换道进行管理,提出了一种三车道有管理元胞自动机交通流模型。并分析了车辆减速概率、换道概率对交通流的影响,结果表明,对超车道上车辆进行管理,并没有改变系统的交通流特性,而是增加车辆驾驶的安全性。

Based on the three-lane cellular automata traffic flow model, a three-lane controlled cellular automata traffic flow model is proposed. The first lane is used for safe overtaking. The analysis focuses on the influence of deceleration probability and lane-changing rate. It is shown that managing vehicles on the passing lane, has not changed the systematic traffic flow characteristic, but is helpful to increase the safe driving.
